Alan Brenner RIM

Two additional executives have left Research In Motion following the company’s poor fourth quarter earnings report last week. RIM confirmed to Bloomberg on Friday that Alan Brenner, the senior vice president of RIM’s BlackBerry platform, and Alistair Mitchell, one of RIM’s vice presidents focused on its BlackBerry Messenger (BBM) service, are departing from the firm. Mitchell has reportedly already left and Brenner is still in a “transition period,” Bloomberg said.

On March 29th, former RIM co-CEO and director Jim Balsillie announced that he was leaving the company along with RIM’s former chief technology officer David Yach and the company’s former chief operations officer Jim Rowan.

RIM CEO Thorsten Heins said last week that he was planning to get rid of high-level staff and that RIM is considering a number of options in an effort to turn its ship around, including licensing its patents, forming a joint venture with another firm or an outright sale. The Canadian government, however, may stand in the way of some of those options.
